SPECIFICATION forming part of Letters Patent No. 707,200, dated August19, 1902.

Application filed September 20, 190 l--" Serial No. 75,917. (No model.)I

To all whom it may concern: I

Be it known that I, SIDNEY W. BOLLINGER, a citizen of the UnitedStates,residin g at Pittsburg, in the county ofAllegheny and State ofPennsylvania, haveinvented or discovered new and useful Improvements inCar-Hauls, of which the following is aspecification.

In the acc'ompanying'drawings, which make part of thisspecificationfFigure I is a side elevation of the'down-haul chain,showing the 1g. II is a detail perspective oflinks and hooks. Fig. IIIis a cross-section on line III III of Fig. I, showing a hook raisedandits bottom in contact with the supporting-plate; f Fig. IV is across-section on line IV IV of Fig.1, showin g a hook lowered and itslower end'between the guides.

The object of my invention, generally stated, is to provide means forthe automatic handling of mine-cars on the down-haul chain of acar-haul.

section of the chain to the downgrade and also for controlling carswhile on the downgrade.

In the accompanying drawings,1 represents. an endless chain. 2 is anidler-wheel, and 3 3 are sprocket-wheels located at each end of theloop. Only one is shown in the drawings.

The chain 1 consists of links arranged in pairs and at suitablepoints,having pivoted 1 hooks 4: and 5, arranged so as to engage the.

car 6 in opposite directions.

Hook I is pivotally connected to the links 7 7 and is provided with anoverbalanced end 8. V

. Hook 5 is pivotally secured to links 11 11 by means of pin 12.

13 is aslot in the forward end of hook 5. in 14, secured to the linklll11, passes through slot 13 and acts as a stop in the swinging movementof said hook. Preferably these thelinks without departing from myinvention.

15 represents a support for chain 1.

-; 16 is a slot formed between the downwardlyextending flanges ofsupport 15.

17 is a channel-shaped guide for the chain 1 on the downgrade portion ofthe chain.

In'the operation of my invention a car after being unloaded'and returnedin the usual manner over the customary cross-over switch andextension-track runs by gravity down and over'sprockefiwheelfi and alongthe rails (not shown) ateach side of chain 1. The inclination of thetrack at position 9 causes the car to-slow -down andstop. As the car 6ismoving forward over the chain 1 to its stopping position bar 10, which.is secured .to the car, will knock down andpass over hook 4, after which:thehook immediately assumes its proper position.

. In the chains forward travel the hook 4. engages the bar 10 of car 6and moves the car forward and over the idler wheel 2. Hook 5afterzopassing over sprocket-wheel 3 drops to its lowest position, whichpermits the bar 10 to pass over. The lower portion of'the hook entersthe slot 16 and travels along said slot untilidler-whe'el 2 is reached,when it raises up out of the slot and assumes its highest p0-sition,remaining up and next enters the channel 17. The bottom of thechannel holds the hook up in position to engage bar 10. After hooket haspushedcarti over the idler-wheel 2 the car pitches forward slightly andthe bar '10 comes into contact'with hook 5, holding v ;the car in checkand traveling down the grade {at whatever speedthe chain travels.

Having describedmyginvention, I claim- 1. In acar-haul, achain, hookspivotally secured thereto and arranged so that alternate hooks engage astop on a car in opposite directions. 1

'2. In a car-haul, abhain-support, a slot in said support, a chain, ahook pivotally secured to said chain anda second chain-support, saidchain-supportsiand said slot providing means for lowe'ringiand raisingthe end of said hook.

3. In a car-haul chain, a hook pivotally secured at one end to the linkof said chain, a Signed at Pittsburg this 18th day of Sepslot in saidhook and a pin through said slot tember, 1901. and secured to said link.

4. In a car-haul, a cai'havinga, stop, a chain, 5 a hook pivotallysecured thereto and means Vitnesses:
